When the top cover 12 is rotated by an external force, the first annular protrusion 1212 rotates and drives the main body of the torsion spring 4 to twist and generate torque, so as to apply force to the top cover 12 in the opposite direction to the rotation of the top cover 12.

[0038] In some embodiments, the base 11 is provided with a receiving cavity 11a and a mounting hole 11b. The receiving cavity 11a is connected to the mounting hole 11b, and the mounting hole 11b is provided at one end of the base 11 facing the top cover 12, and the mounting hole 11b is connected to the connecting hole 122a.

[0039] In some embodiments, the base 11 includes an upper shell 111 and a lower shell 112. The lower shell 112 is disposed at one end of the upper shell 111 facing away from the top cover 12. The upper shell 111 and the lower shell 112 are detachably connected to form a receiving cavity 11a.

[0040] In some embodiments, the detachable connection method includes snap connection, threaded connection, etc.

[0041] In some embodiments, the outer surface of the circuit board 3 is covered with a sealant layer (not shown). The sealant layer is used to seal and protect the electronic components on the circuit board 3.

[0042] In some embodiments, a sealant is poured into the gap between the inner surface of the receiving cavity 11 a formed by the base 11 and the circuit board 3 to form a sealant layer on the surface of the circuit board 3 .

[0043] In some embodiments, a connecting protrusion 1111 is provided on the surface of the upper shell 111 facing the top cover 12, and a plurality of grooves 111a are provided around the connecting protrusion 1111. A connecting cavity connected to the receiving cavity 11a is provided in the connecting protrusion 1111. The mounting hole 11b is provided at the end of the connecting protrusion 1111 facing the top cover 12, and the mounting hole 11b is connected to the end of the connecting cavity away from the receiving cavity 11a. Two oppositely arranged hooks 1214 are provided on the inner surface of the opening of the outer shell 121 facing the receiving cavity 121a, and the hook heads of the two hooks 1214 are inserted into the mounting holes 11b and are connected to the inner wall of the connecting cavity facing the receiving cavity 11a, and the two opposite surfaces of the two hooks 1214 are arc surfaces matching the mounting holes 11b, so that the top cover 12 is fixed to the base 11 and the top cover 12 can rotate relative to the base 11.

[0044] In some embodiments, the knob device 1000 further includes a spring 5, a first end of the spring 5 is connected to the top cover 12, a second end of the spring 5 is connected to the base 11, and the spring 5 is used to apply elastic force to the top cover 12 in the direction from the base 11 to the top cover 12. The opposite force provided by the spring 5 enables the user to feel a certain resistance when pressing the top cover 12, so as to improve the hand feeling when pressing the top cover 12. On the other hand, the spring 5 can also play a role in resetting the top cover 12, and after the external force acting on the top cover 12 is removed, the top cover 12 automatically resets to the initial position when the user presses the top cover 12.

[0045] In some embodiments, the second end of the spring 5 is sleeved on the connecting protrusion 1111, and the second end of the spring 5 abuts against the surface of the base 11 facing the top cover 12. The first end of the spring 5 is located in the cavity formed by the inner circumferential wall of the first annular protrusion 1212 and the third annular protrusion 1222, and the second end of the spring 5 abuts against the surface of the housing 121 facing the base 11.

[0046] In some embodiments, the first magnetic body 2 is annular, the central axis of the first magnetic body 2 coincides with the rotation axis, the first magnetic body 2 includes sixteen equal magnetic poles, and the N poles and S poles in the sixteen equal magnetic poles are arranged alternately in the direction around the rotation axis. The first magnetic sensing element is a Hall sensor, and the number of Hall sensors is two. When the first magnetic body 2 rotates with the top cover 12, the two Hall sensors are used to sense the magnetic field changes generated when the first magnetic body 2 rotates. When the top cover 12 rotates and drives the first magnetic body 2 to rotate around the rotation axis, the alternately arranged magnetic poles with opposite polarities approach and move away from the first magnetic sensing element in turn, so that the first magnetic sensing element can obtain a periodic waveform for judging the rotation direction of the top cover 12. Since the first magnetic body 2 includes sixteen equal magnetic poles, when the user rotates clockwise at least 45° or counterclockwise at least 45°, the Hall sensor can collect waveforms that meet the judgment conditions for the control panel of the smart toilet to judge the rotation direction of the top cover 12, and then control the toilet to perform corresponding functions according to the rotation direction. For example, when the user rotates the top cover 12 at least 45° clockwise, the toilet starts the butt wash function, and when the user rotates the top cover 12 at least 45° counterclockwise, the toilet starts the feminine wash function.

[0047] It is understandable that the first magnetic body 2 is not limited to the above-mentioned sixteen equal magnetic poles. For example, in some other embodiments, the first magnetic body 2 can also be thirty-two equal magnetic poles. Along the direction around the rotation axis, the number of magnetic poles of the first magnetic body 2 can be selected according to actual conditions.

[0048] In some embodiments, the knob device 1000 also includes a base 6 and a telescopic mechanism 7. The base 6 is provided with a receiving groove 6a, which is used to receive the knob assembly 1. The telescopic mechanism 7 is connected to the knob assembly 1, and is used to drive the knob assembly 1 to extend out of the receiving groove 6a or retract into the receiving groove 6a.

[0049] In some embodiments, the telescopic mechanism 7 includes a driving motor 71, a reduction gear set 72, a nut seat 73 and a screw 74, the output end of the driving motor 71 is connected to the reduction gear set 72, the nut seat 73 is provided with an internal thread, the nut seat 73 is connected to the reduction gear set 72, and the screw 74 is connected to the base 11. The driving motor 71 drives the gear of the reduction gear set 72 to rotate to drive the nut seat 73 to rotate, thereby driving the screw 74 to extend from the bottom of the receiving groove 6a to the direction of the notch of the receiving groove 6a or to retract from the notch of the receiving groove 6a to the bottom of the receiving groove 6a, thereby making the knob assembly 1 extend from the receiving groove 6a or retract into the receiving groove 6a. When the knob device 1000 is applied to a smart toilet, the smart toilet extends when it senses that the user has the intention to use the toilet, and retracts back to the receiving groove 6a after use. The knob assembly 1 can not be exposed on the toilet surface when the smart toilet is idle, thereby improving the overall aesthetics of the smart toilet. When in use, the way in which the knob assembly 1 extends and retracts increases the sense of human-computer interaction and improves the user experience.

[0050] It can be understood that the telescopic mechanism 7 is not limited to driving the knob assembly 1 to move by providing a driving motor 71, a reduction gear set 72, a nut seat 73 and a screw 74. In some other embodiments, the telescopic mechanism 7 can also drive the knob assembly 1 to extend out of the receiving groove 6a or retract into the receiving groove 6a through a hydraulic transmission structure.

[0051] In some embodiments, a touch switch is provided at the top cover 12 of the knob assembly 1 , the touch switch is electrically connected to the circuit board 3 , and the touch switch is used for controlling the knob assembly 1 to extend out of the receiving groove 6 a or retract into the receiving groove 6 a after being touched by a user.

[0052] In some embodiments, the touch switch includes but is not limited to a capacitive touch switch.

[0053] In some embodiments, the smart toilet senses whether the user is willing to use the toilet by setting a microwave sensor to detect whether the user is close to the toilet, or by setting a pressure sensor to detect whether the user is sitting on the toilet seat.

[0054] See also Figure 5In some embodiments, the knob device 1000 further includes a second magnetic sensing element (not shown), a second magnetic body 8 and a third magnetic body 9. The second magnetic sensing element is disposed in the knob assembly 1, the second magnetic sensing element is connected to the circuit board 3, the second magnetic body 8 and the third magnetic body 9 are fixed to the base 6, and the second magnetic body 8 and the third magnetic body 9 are relatively spaced along the direction in which the telescopic mechanism 7 drives the knob assembly 1 to move. The second magnetic sensing element is used to sense the second magnetic body 8 when the knob assembly 1 moves away from the receiving groove 6a to a preset end position, and to sense the third magnetic body 9 when the knob assembly 1 moves toward the bottom of the receiving groove 6a to a preset end position. The second magnetic sensing element senses the magnetic fields of the second magnetic body 8 and the third magnetic body 9, thereby detecting whether the knob assembly 1 moves to the preset end position.
